Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

Several Kerrville Independent School District teachers and staff members drove school buses full of hundreds of campers from Camp La Junta and Camp Mystic to reunification sites on July 4.

Bud Bolton told FOX Weather Correspondent Robert Ray he lost his home to the Central Texas flooding on July 4. He describes trying to help people being swept away on the Guadalupe River and his son finding the body of a child from Camp Mystic.

The director of Camp Mystic was among the people killed due to the Hill Country floods, according to the Kerrville Daily Times.

The family was reportedly vacationing at a river house in Kerr County as the floods swept through the area unannounced.

Some parents were notified on Friday that their daughters at Camp Mystic, an all-girls Christian summer camp, had gone missing after devastating flash floods tore through south-central Texas.
